I've just noticed that my Quad files (such as old Pink Floyd mixes) were only playing back in Stereo (not downmixed, just the front L/R channels). I went to Tools > Options > Audio > DSP & Audio Format and saw that "Source Number of Channels" was selected. I would assume that would mean that playback would be exactly as the album's mixer had intended.
I did some research on this board, and saw an old post where someone recommended changing the number of channels to 5.1 (my system consists of a Mac Mini connected via HDMI to a Marantz 8805 Pre/Pro. My surround setup is Atmos 5.1.4). I made the change, and now get surround from those Quad mixes, but sound also comes from the Center channel, so this is obviously getting reprocessed as 5.1. Is there a way to hear it exactly as it was intended? Shouldn't "Source number of channels" mean that the mix comes through exactly the way it was meant to? Now I'm getting paranoid that JRiver is reprocessing all my music into its own funky mixes, and I want to make sure I'm hearing mixes as they should be.
Thanks in advance!
